Abstract
Systems and methods for logically organizing data for storage and recovery on a data storage medium using a multi-level format are described. Embodiments include systems and methods for protecting data stored on a data storage medium so that the data may be recovered without errors.
Claims20
A data storage medium including:
- a first partition, the first partition comprising a first contiguous subdivision of the data storage medium within which all data is written in one format and at one density;
- first user data residing within the first partition;
- a second partition, the second partition comprising a second contiguous subdivision of the data storage medium within which all data is written in one format and at one density;
- and
- a first structure residing within the second partition, wherein the first structure describes a host defined logical block address of the first data and a physical address of the first data in the data storage medium.
2 more elements
A data storage medium comprising:
- first user data recorded on the data storage medium;
- a first data structure recorded on the data storage medium, the first structure describing a host defined logical block address of the first user data and a physical address of the first user data on the data storage medium;
- a second data structure recorded on the data storage medium, the second data structure describing the host defined logical block address of the first data and the physical address of the first data on the data storage medium;
- and
- second user data recorded on the data storage medium;
- an updated first data structure describing the host defined logical block address of the first data, the physical address of the first data on the data storage medium, a host defined logical block address of the second data, and a physical address of the second data on the data storage medium.
3 more elements
A method of storing data to a data storage medium, the method comprising:
- receiving a first logical block from a host, the first logical block including first data;
- writing the first data to the data storage medium;
- creating a first data structure, wherein the first data structure describes a host defined logical block address of the first data and a physical address of the first data on the data storage medium;
- writing the first data structure to the data storage medium;
- creating a second data structure, wherein the second data structure describes the host defined logical block address of the first data and the physical address of the first data on the data storage medium;
- and
- writing the second data structure to the data storage medium.
